Yes. If you put water and hexane in a beaker or a container together, the hexane will be on top of the water. One way to see this is to dye the water. They do not mix because water is polar and the hexane cannot dissolve in it. It is on top because, guess why? It is less dense than water. That is why anything floats on water... it is less dense! Hope that answers your question!

Why does a needle float on water but not on hexane?

Technically, a needle is heavier than water, so it doesn't really float in the usual sense of the word. It is suspended by surface tension between the water molecules on t

Why is hexane not soluble in water?

Why is hexane soluble in water and gasoline is not?

Hexane and gasoline both are insoluble in water.

How do you separate hexane and water and ethanol?

phase separation. the two solvents must have similar polarities and b.p.'s - no crystals would form...and if for some reason they did, they would be impure

Why do water and hexane do not mix?

Water is a polar molecule (is a dipole, has a positive end and a negative end), hexane is a non-polar molecule. Like dissolves like. Water will dissolve other polar molecules,

Why is ethanol soluble in water and hexane?

Ethanol is soluble in water because the -OH group of ethanol (CH3CH2OH) can form hydrogen bonds with water. Hydrogen bonding occurs when a very electronegative molecule like O
